Re: I don\'t even know what I have!
Do you have aftermarket wheels, if so your offset(backspacing) might be funky and that might be causing the rubbing
Also even with your tire that close to your mudflap does it rub there too or only on the frame, I too have 31" tires but mine are real 31s, yours look to be a little bigger than 31s as stated above in the other post
I no my tires are pretty close to my mudflaps but I never rub ever
As for lifts...
BL, Body Lift- raises body up of of frame to give desired lift height, mainly used to clear tire if rubbing if already lifted via suspension and you need that little extra inch of room or inches
Suspension- includes coilovers, coils, spacers, kits like the fabtech/procomp/trailmaster that give 4"/6"/6" of lift via new locations for the control arms
coils-OME, Old Man Emu products, give up to 3" depending on what you by, good and decent price
coilovers- SAWs, Donahoe, Fabtech, KING, etc., great but pricey, also adjustable
feel free to ask as many questions as you need
Take note I did not cover anything for reat setups
